摘要

基于地震波传播的三段几何衰减模型,在Matlab平台下开发体波Q值求解计算程序。该程序直接读取地震sac数据记录、仪器参数文件,根据仪器参数文件生成仪器幅频响应,对地震S波数据记录实现去仪器响应、去噪声后,得到其位移幅度谱,对多个台站地震记录位移谱进行反演,求取体波Q值。该软件实现以上算法的系列流程,并利用相关控件优化使用者的数据处理过程,操作简单方便,同时根据地震实时产出Q值,有助于分析震前、震后区域Q值变化,积累地震预报经验。
        Based on the three part decaying model during seismic wave transmission, we develops the software of calculating Q value in the Matlab platform. This software can directly import the seismic data with sac-format and the seismic instrument parameter file. The software can complete all the procedure of calculating Q value, calculating the displacement spectrum and fitting the relationship between Q value and frequency f. after eliminating instrument response and noise. This software use many control interfaces in which the operating panel is very convenient for user to figure out Q value quickly based on the real time seismic data which can benefit to analyzing the variation of Q value before and after the seismic occurring.
